Hovorka, TwinFalls, Idaho I ApplicationNovember 6, 1939; sem No. 303,131 7 4 1 Claim:(01. 240-521) M My invention relates to improvements in service lamps ofthe electric light type, for attachment more particularly to variousparts of automobiles although, as will presently appear, it is alsoadapted for general application to benches, beds,

and various other objects.

The primary object'of the invention is to provide an electric lightsupport adapted to clamp to bolts, rods, or other roundparts, ofdifferent sizes at various angles to the axis of the parts and whichprovides for universal adjustment of the light into different setpositionson the support, is easy to attach, of strong construction, andinexpensive to manufacture.

To the accomplishment of the above, and subordinate objects presentlyappearing, a preferred embodiment of my invention has been illustratedin accompanying drawings, set forth in detail in the succeedingdescription, and defined in the claim appended hereto.

In said drawings:

Figure 1 is a view in side elevation of the preferred embodiment of theinvention,

Figure 2 is an inverted plan view of one of the jaw-carrying arms,

Figure 3 is a view in transverse section taken on the line 3-3 of Figure1, looking in the direction indicated by the arrows,

Figure 4 is a fragmentary inverted plan view of the other jaw-carryingarm,

Figure 5 is a similar view of the inner end of said other arm,

Figure 6 is a view in perspective of the jaw tensioning spring,

Figure 7 is a view in edge elevation of the fastener for the shade andhood unit,

Figure 8 is a view in longitudinal section taken on the line 8- 8 ofFigure 1 looking in the direction indicated by the arrows and drawn toan enlarged scale, and

Figure 9 is a view in transverse section taken on the line 9-9 of Figure1 looking in the direction of the arrows.

ends thereof terminate in a pair of opposed in-' turned flanges 5extending across said ends'and forming teeth for grippingopposite'sid'esof a shelf, ledge or like device. A split ring 6 'of'flatresilient metal is interposed between the end portions 3"with its endsengaging the inner ends of the jaws 4 as shown at Figure 1, said ringbeing retained in the channels of said portions 3 by edge lugs as at I,on said portions bent across the edges of said spring. The ring 6, aswill be clear, spaces the arms I, 2 apart, couples the same together andreacts to urge the jaws 4 toward each other into clamping relation.

As will now be seen, by graspingthe inner ends of the arms I, 2, andpressing the'same together, the jaws 4 may be separated to open the sameso that they may be" clamped to a selected part, and upon release ofsaid arms the jaws-4 will clamp the part therebetween under reaction ofthe ring 6. As will also be clear, by virtue of the arrangement of thering 6 in the end portions 3, the jaws 4 will open wide since the ring 6opens up at its ends.

Each jaw 4 is provided in the longitudinal center thereof, on its innerface, with a groove 8 and also with a pair of diagonal side grooves 9diverging from the front ends of the groove 8. The grooves 8 arecomplemental to each other whereby they are adapted to receive a bolt,rod, or the like, therein so that the arms I, 2, may be clamped to oneend of the same to extend therefrom parallel therewith. The pairs ofgrooves 9 are also complemental each to the other so that said arms 4may be similarly clamped to the bolt, or red, to extend therefrom atdifferent angles as will be manifest.

A sleeve-like coupling I0 is secured to the inner face of the arm I,adjacent the inner end thereof by a pair of diametrically oppositecentral studs I I on the coupling and a pair of apertured edge lugs I2on said arm receiving the studs, the coupling, as best shown in Figure1, fitting into the channel of the arm. A suitable length of BX cable I3is extended at one end through an apertured lug I4 on the inner end ofsaid arm I and turned into one end of the coupling I0 against anapertured partition I5 in said coupling. The other end of the cable I3has attached thereto, in any suitable manner, the conventional lightsocket I6 having the usual neck part I! for receiving an electric lightI8. The usual lead cable I9 extends from the socket I6 through the cableI3 and through the partition I5 of coupling III for connection of theusual plug in line 20 thereto. The plug-in line 20 is extended throughan apertured lug 2| on the inner face of the arm I and provided with theconventional form of spring connector 22 interposed between the lug 2|and coupling l and adapted to screw into the coupling in a well-knownmanner. The usual connection between the line 20 and the lead cable I9is designated at 23.

A combined shade and guard unit 24 for the light l8 and socket I5,respectively, is provided, said unit comprising a concave, oval shadepart 25 partially surrounding the light I8, a reduced intermediate part26 fitting part-way around the neck I! and a rear hood part 21 ofsemicircular cross section fitting part-way around the body of thesocket l6 and having a central enlargement 28 for accommodating theswitch button 29 of the socket when the unit is rotated around saidsocket and ligiht. The described, unit is rotatably mounted on the cablel3 by means of a sleeve 30 extending from the hood part 2'! and ofsemicircularcross section, substantially, for fitting over said cable,the sleeve terminating in an end flange 3!. A coil spring 32 surroundingsaid sleeve and cable secures the former to the latter so that the unit29 may be rotated about the: cable l3, socket I6 and, light 18 asdesired. To further secure the unit 24 in proper position a split,ring-like clasp 33 is provided for surrounding the part 2.6 and neck 11,said clasp; being of resilient metal and provided on one end with abutton 34 and on its other end with a hook fastener 35 adapted to snapover the button 34.

As will now be seen, in any position in which the arms I, 2 of thedescribed pincer-like support are clamped to an object, the light 18 maybe universally swung on the arm I to difierent set positions by bendingthe-cable 13. Also the unit 24 may be rotated into any desired positionto shade the light [8 from any angle. The manner in which the clampingjaws 4 are operated has been set forth. It may be further explained,however, that said jaws 4 are also adapted to rigidly clamp to objectsof flat and other shapes, the grooves 8, 9, facilitating gripping bysaid jaws and the teeth 5 coacting to further facilitate such grippingaction.

The foregoing will, it is believed, s fi ce to impart a clearunderstanding of my invention without further explanation.

Manifestly the invention, as described, is susceptible of modificationwithout departing from the inventive concept, and right is hereinreserved to such modifications as fall within the scope of the subjoinedclaim.

What I claim is:

In a lamp, a pincer-like support for clamping to a fixed part comprisinga pair of elongated arms spaced apart in a common plane in opposedrelation and having substantially semi-circular outer end portionsoppositely bowed and internally channeled and terminating in a pair offlat T-head extensions forming a pair of opposed clamping jaws saidextensions having rightangled innerendsextending in between said bowedportions and providing a pair of opposed clamping teeth on said jaws, apair of inturned lugs on each bowed portion, respectively, a splitresilient ring fitting into the channels of said portions and extendingbetween said pairs of lugs and having the ends thereof bearing on saidinner ends of the jaws, respectively, whereby said jaws are yieldinglyurged into clamping relation for relative separation by manipulation ofsaid arms, and a lamp bulb mounted on one of said arms.
